Fluoroplastic heat exchanger

1. Brief introduction

Manufacturing technology of fluoroplastic heat exchanger is a manufacturing method of fluoroplastic heat exchanger with Fluoroplastic tube as heat exchange tube bundle and fluoroplastic rod, cake or plate as heat exchange tube sheet. All the plastics containing fluorine atoms in the molecular structure are called fluoroplastics. Fluoroplastics are prepared by homopolymerization or copolymerization of fluoromonomers such as tetrafluoroethylene, hexafluoropropylene, chlorotrifluoroethylene, vinylidene fluoride and fluoroethylene. With the continuous development of polymer technology, the varieties of fluoroplastics are gradually increasing, and the application scope is expanding. Due to the fluorine atoms in the molecular structure of fluoroplastics, they have many excellent corrosion and temperature resistance properties. In addition to molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid fluorine, polytetrafluoroethylene can resist the corrosion of all other chemicals, and has the corrosion resistance that can not be changed even when boiling in aqua regia. In addition, due to poor surface wettability and small surface energy, other objects are difficult to adhere to its surface, and it has the most ideal temperature resistance, non stickiness, flexure, adhesion resistance of all fluoroplastics Anti aging properties and excellent performance price ratio are widely used in all kinds of occasions that need acid and alkali resistance and organic solvents. They are ideal materials for corrosion resistant heat exchangers.

manufacturing technology of fluoroplastic heat exchanger is mainly made of polytetrafluoroethylene heat exchanger or FEP heat exchanger, in which polytetrafluoroethylene is also known as Teflon, Teflon or Teflon for short. Although the thermal conductivity of polytetrafluoroethylene is not ideal, because this kind of fluoroplastic heat exchange tube with excellent corrosion resistance uses thin-wall capillary, its wall thermal resistance is small, and the diameter of the heat exchange tube is small (3-10mm), and the fluid in the tube is mostly turbulent, which greatly improves the heat transfer coefficient of polytetrafluoroethylene. Polytetrafluoroethylene heat exchanger can be used not only for heating steam, hot water or heat transfer oil, but also for cooling or condensing. It is widely used in chemical industry, medicine, pickling, electroplating and other industries with strong corrosion. It can be used as cooler, heater, evaporator and condenser.

2. Technical features

manufacturing technology of fluoroplastic heat exchanger is based on more than 30 years of design and manufacturing experience, including a full set of relevant documents, standards and processing technology, including material selection, production equipment, scheme design, drawing design, manufacturing, quality control, etc. The key to the manufacturing technology of fluoroplastic heat exchanger is welding between fluoroplastic tube sheet and fluoroplastic tube bundle . This technology adopts advanced one-time integral welding, which is simple and reliable. Each welding strength is greater than 15kgf. After welding, there is no water seepage in 24 hours under 8kg water pressure
